Thanks! I think I like that one, too, for the reasons you mention. The other (small) city in the tale is called Dry Rivers - the Telaka people tend to work that way, naming their places and families for obvious geographical features. The reason I came up with Newport as a name in the first place was a line from A Town Like Alice, when Jean explains to the barrister that Kuala Lumpur actually just means Newport, and that, once you know a language and understand what the names mean, place names are easy to remember. But Kassin can mean Newport without anyone being the wiser, and it sounds a lot more exotic!
